Thank you to all for your rapid answer.
I saw the fuse in Mouser website, I think the same one is the following:
I also called they and they told me that only after I will put the order they check the real availability in the various site they have and if present they send me, but if not present I have to wait 10 Week as this is the Factory Lead Time.
And more of this the shipping will cost 20€, so a total of 39,80€ for 10 little fuse I think is too much.
I think I will go for the one you suggest. It's cheap, with free shipping and it seems not to big to don't fit in the board.
Now I will have to wait about 1 month before all parts arrive, then I will let you know if fuse will fit or not.
Thank you again for your attention and a big hello from Italy.
